Leviticus 23:15-21

The Festival of Weeks 15“ ‘From the day after the Sabbath, the day you brought the sheaf of the wave offering, count off seven full weeks. 16Count off fifty days up to the day after the seventh Sabbath, and then present an offering of new grain to the LORD . 17From wherever you live, bring two loaves made of two-tenths of an ephah of the finest flour, baked with yeast, as a wave offering of firstfruits to the LORD . 18Present with this bread seven male lambs, each a year old and without defect, one young bull and two rams. They will be a burnt offering to the LORD, together with their grain offerings and drink offerings—a food offering, an aroma pleasing to the LORD . 19Then sacrifice one male goat for a sin offering Or purification offering and two lambs, each a year old, for a fellowship offering. 20The priest is to wave the two lambs before the LORD as a wave offering, together with the bread of the firstfruits. They are a sacred offering to the LORD for the priest.

21On that same day you are to proclaim a sacred assembly and do no regular work. This is to be a lasting ordinance for the generations to come, wherever you live.
